I have a different suggestion, if I may ;)
:s/^\s*\(.\{-\}\)\s\+\(\*.*\*\)\s*$/\=printf("%s%*.s%s", submatch(1),
((&tw?&tw:&wm?winwidth(0)-&wm:winwidth(0)) -
len(split(submatch(1).submatch(2),'\zs'))), ' ', submatch(2))/

This should be a little bit shorter and should work with multibyte glyphs
as well.
